Specification of Letters Patent. Patented Aug, 13, 1918. Original application filed April 23, 1913, Serial No. 763,047. Iatent No. 1,104,472, July 21, 1914. Divided and this application filed June 25, 1914. Serial No.847,201.

To all whom it may concern: v

Be i known that I, GEORGE C. BREIDnR'r, a citizen of the United States, residing at Chicagdj inthe county of Cook and State of Illinois, .have invented certain new and usenumbered respectively 1,097,387 and 1,099,.,

838. Ventilatorsof this type consist of boxlike structures adapted .to be arranged on ,the outside of a railway car, for example, on

the deck 'of the car, projecting horizontally from the deck sash, if the car be of the monitor deck construction, and are provided with one or more, preferably two, air collecting or ramming faces disposed substantially at right angles to the line of travel of the car, and with exhaust passageways communicatingwith the car and terminating at the edges of said. air ramming faces. The air collected or impinging against the forward air 4 ramming face of the ventilator when the car is in motion is forced to make a substantially right angle turn over the edges of the same along said exhaust openings and creates a suction through the exhaust passageway or passageways of the ventilator which withdraws the foul air from the car.

The present invention has for one itsprincipal objects toprovide certain novel conlstructions, arrangements and devices in a ventilator of this type whereby the ventilating function is effectively performed without danger of choking and whereby the openings or'passagew'ays from the car to the ventilator are protected against the possibility of an outside wind blowing into the car through the ventilator.

A further object of the invention is to provide' a'ventilator which will be inexpensive to manufacture.

A further object isto provide, in a vcntilator ofthis type, a valve which, if need be, may be closed so as to stop the operation of the ventilator. I

1 The invention has for further obj'ectsthe provision of such other improved arrangements, constructions and devices in ventilators for railway cars, or other moving structures, as will be hereinafter described and claimed. 1

The invention is illustrated, in certain preferred embodiments, in the accompany tive, ofthe end of a car of the monitor deck type with the ventilator shown in Figs. 1

and 2 attached to'the deck sash.

4 is a vertical sectional view of a modified form of ventilator constructed in principles of the inaccordance with the vention.

Fig. 5 is a sectional 5-5 of Fig. 4:.

Fig. 6 is a view, in perspective, of another modified form,

Fig. 7, a side elevation I Fig. 8, a sectional plan taken'on line 8 plan taken on line of Fig. 7, and

Fig. 9, a sectional view on line 99 of Fig.

Like characters of reference designate like parts in the several figures'of the drawings.

Referring firstto Figs. 1, 2 and 3, 25 deslgnates a railway car of the monitor deck type to the deck sash 26 of which the ventilator is attached. The ventilator consists, in this embodiment of the invention, of a box like structure formed with an outer imperforate end 27, a pair of oppositely disposed air ramming faces 28, and an inner side or base 29 having a central opening 30 and provided around this opening with a neck 31 having a flange32 for attaching the ventilator to the deck sash v26. The other two sides of the/structure are open and are provided with sets of substantially parallel louvers Projecting inwardly from the "base 29 is a flange or rim 34 constituting, in effect, a continuation of the neck 31. The

structure is arranged on the car, as will be seen from Fig. 3, so that the air ramming faces 28 stand substantially at right angles to the line of travel of the car, one face coming into action when the car moves in one direction, the other when the car moves in the opposite direction. I have shown the faces 28 as having the configuration described and claimed in my Patent No. 1,099,888 referred to above, whereby the air collected thereon is prevented from spilling over the edges lying along the imperforate outer end 27 and is directedtoward the edges lying along the exhaust openings inthe top andbottom ofthe ventilator. The louvers 33 are preferably inclined toward the outer imperforate end faces 27, the inner edges35 of the louvers being preferably given a slight bend toward the same. The imperforate end is preferably bowed or convex exteriorl'y. Bythis arrangement cinders, rain and the like, fallln'g through the ventilator when positioned as shown in Fig. 3, are deflected away from the opening leading to the car. Moreover, the arrangement prevents any possible choking of the. ventilator. This is particularly so if the ventilator, as isconteinplated by my invention, is arrangedin a vertical position. on top of the. car (in. the position of they ventilator shownin Fig. 4). In such position a side. wind will blow through the ventilator from one side to the other. In such case, the louvers being oblique, deflect thewind toward the. outer, in

this case the upper, endof the ventilatorso.

that the cross draft. does not check the out? flow from the car. The bulging or convexity of the end gives additional space in. the center of the ventilator, that is, opposite. the opening 30 through whichthe stream of exhaust air passes. The flange 34preferably.

has an inward inclination and then is flared, as indicated at 36, so thatthe. currents of foul air are directed out through thespaces between the louvers The construction shown in Figs. 4 andp-5 is intended more especially tobe mounted on the top of the car. of the roof of a car on which the ventilator is mounted with its air ramming. facesg38 disposed at right angles totheline of travel of the car, one facing the front and 'the. The

other the back. The top. 39 is fiat. neck 40 is. shown as circular and also-the opening 41 in the base42. In theopen sides,

ofthe ventilator, are. arranged three-sided structures 43, the exterior sidesof which do not project out beyond the outer edges of the air ramming. faces 38. The transverse walls 44 of these structures,terminate .in.

curved bends 45. Between these walls. and theair ramming faces 38 are sets of parallel louvers 46, the louvers nearest the walls 44 being .the. narrowest and the others pr0-.

gressively widen. The air rammingfaces 38 are depressed sov as to form projections 47 between the air collecting portions of the air ramming faces. and the top and base plates 39,42. These projections check the waste of air over .the upper andlower edges.

of the air ramming faces, The. curved. or lip portions. 45.0f the walls .44 do not project down to the base. member-42. vIn the space.v

below the lips are arranged curved-strips 48 provided attheir upper edges with out-. turned angle pieces 49. This arrangement preventsv waterv from entering. the. car through opening 41. I

37 designates one end.

.rests upon a spider secured to the walls.

44. By turning rod 52, which for that purpose is provided witha handle 56, the valves 50may be made to close the openings between the three-sided structures 43 so as to put the ventilator out of operation: This ventilator might beset in horizontal position instead ofin the vertical 'position'shown' ifdesired.

Figs." 6 to 9 inclusive show another modi fied' construction built, however, upon the.

same general principles; This ventilatoris intended particularly to be put flatwise on the top of a car-and therefore is not shown,

as provided with'a neck although it might be constructed with a neckand-placed in the same position as the ventilator shown in Fig. 3. The'structure as shownconsists of a bowed or exteriorly convex imperforate. upper or outer end 57, ajbase 58 having-an opening 59 communicating with'the interior of the car, and oppositely disposed air ramclined ward imperfqrstef pp r. nd- 7 ming faces 60. Each open 'sideji's provided with a set of vertical louvers Bland within. the same a second set. of horizontally; disof the structure. The lowermostjoif these,
